EYEGLASSES.

Patented Apr. 27, 1920.

Application med january 2, '1920. semi-Nb. 348,791.

I especially to eyeglasses; and the object of the same is to improve the mechanism for permitting folding of the glasses and latching of the saine in overlapped position.

To this end the invention consists specilically in a novel form'of catch as will be described below and as shown in the drawings wherein:

Figure 1 is an elevation of a pair of eyeglasses equipped with this invention, the same being open.

Fig. 2 is an enlarged section through the glasses when folded, and through the catch which holds them in folded condition.

Fig. 3 is a 'detail showing certain parts of the catch.

The lenses L are mounted within bows B which are connected by a spring S and carry cess 3 within the handle H and held therein 16 fixed transversely across the casing, the

slot being of a length to permit the spring v the handle for that purpose.

to throw the notches normally out of register or to permit pressure on the head 1() of the bolt to bear the latter inward and throw kthe notches into register.

)This entire structure is mounted in the recess 3 in the handle as stated, its notch 2 facing toward the bow B which carries said handle and yet spaced therefrom a sufficient distance to permit the passage of a tongue 17 which projectsfrom the keeper K, so that as the glasses are folded the tongue will be projected through the notch 2. LThis tongue tapers to its tip as at 18 and its body is notched as at 19. In its passage through the notches 2 and 12 it causes the bolt to slide inward and compress the spring 13, and when its notch 19 has passed the bolt, the latter is projected by its spring as far as the length of its slot 15 will permit, and the tongue is fastened so that the glasses are held in this condition. To open them, it is only necessary to press on the head or knob 10, and when the latch releases the tongue of the keeper, the spring S causes the glasses to fly open. y

Attention is invited to the fact that all parts of this device are movably mounted in the recess 3 in the handle by a single fastening means such as the screw 4, and whenythe catch needs attention b f way of cleaning or repair, it is taken bodily out of Such handle may be of shell or precious metal, and it is l obviously wise to remove all ,mechanism therefrom .while working on it so that the handle will not be heated or accidentallv struck orV scratched by the tools. While I have shown the casing 1 as 'substantially rectangular, it may be given other external configuration so as to adapt it to a recess 3 Of appropriate shape. Whatever the material of the handle, it is only necessary to provide it with this recess and with the little hole, into the bottom of the recess for the passage of the fastening device 4, and thereloo fore work on an expensive handle is minimizedwith a consequent reduction in the chances of breaking it.

What is claimed as new is:

A folding eyeglass frame including a keeper on one lens bow having a notch inone edge and a tapered tip; combined with a handle on the other bow provided with a recess, a box-like casing having a notch acrossrone edge and open at its outer end,

a screw through the handle into the bottom of said casing, a bolt sldably mounted in the casing and having a notch across one edge adapted to aline With that mentioned and a longitudinal slot in its body and a cavity in its lower end, its outer end pro-v jecting beyond the casing and having a knob7 an expansive spring Within said cavity restlng on the bottom of the casing, and a pin across the casing through said slot, for the 10 purpose set forth. Y

In testimony whereof I affix my signature, in the presence of tWo Witnesses.
